Just thought I'd chime in regarding the attractiveness: From my perspective, a woman's confidence and her apparent happiness carry a ton more weight than her physique does, A happy confident woman can look quite attractive regardless of her 'looks'. Don't get me wrong, looks play a decent sized role in the initial attraction, especially if she isn't as confident as she could be. Me, I'm a sucker for a pretty face, so I guess you could say that is the most important physical attribute for me. I also prefer taller women, about 5'9 or taller.
Anyway, I digress, My thought is the physical attraction is what gets the ball rolling, but as we grow together, the physical becomes less important: an emotional connection seems to make the flaws in her physique blend into the background.
Regarding chasing young women, well yeah, they are attractive...until you spend a few minutes talking to them and realize that there is no shared history. If I were looking, I'd be looking for someone close to my own age (I'm 44)...someone who grew up in the 60's and 70's, someone I could relate to. Sorry, I just wouldn't be interested past the obvious eye candy in someone who would not be able to relate to my past.
